Sure 'nuff, it's transmitting a tone for a few seconds every
minute-and-a-half.  Interestingly it keys up the TX for a second or two
before the tone starts.

Orbit 124 passed directly over the UK Midlands, placing Maison MM3YEQ
just a little north of the centre of the footprint as it went directly
west to east.  Absolutely booming signal.
